Automatic unit detection
ImpARial recognises the unit on its own (grams, millilitres, centimetres, degrees) and picks the right conversion for you.
Work with photos too
Saved image? Pick it from your library and ImpARial converts the units it finds inside.
Collect & share results
Every conversion lands in a results list. Share a single line, or export the whole set at once.
20+ units, 7 categories
Distance, weight, temperature, speed, volume, area and pressure: the metric and imperial pairs you meet in real life.
Rotate freely
Portrait or landscape, the overlay follows the device so wide labels and long lists stay readable.

FAQ
Good to know
What does ImpARial cost?
It depends on the store. On the App Store the app is free to download, with an optional subscription available as an in-app purchase. On Google Play it is a paid app: you buy it once, there is no subscription and nothing is limited. Current pricing is always shown on the store page.
Which devices does it run on?
ImpARial runs on iPhone and iPad with iOS 16.4 or later. An Android version is also available on Google Play.
Do I have to pick the unit myself?
Usually not. Detection is automatic: ImpARial recognises the unit written next to the number and converts it, with no menus and no typing. When a number appears without a unit beside it, you can pick the conversion manually and ImpARial applies it to whatever you point at.
Can I convert something from a photo?
Yes. Besides the live camera, you can hand ImpARial an image from your photo library and it will convert the units it finds in it.
Can I keep the results?
Conversions are collected in a results list. Share any single line, or export them all together.
Which units are supported?
Over twenty metric and imperial units across seven categories: distance, weight, temperature, speed, volume, area and pressure.
